Title: X-ray mirror device
Inventor: SUZUKI YOSHIO
IPC: G21K1/06
Filed: 1994-09-30
Abstract: PURPOSE: To obtain an X-ray reflective condenser mirror having a highly accurate mirror face of arbitrary shape by pressing a thin plane mirror against a base, previously worked into a desired shape, through vacuum suction. CONSTITUTION: A thin reflector 1 is mounted on a base 2, worked into a desired concave plane, and then the base 2 is evacuated by means of a vacuum pump 3 through a hole thus bringing the reflector 1 into tight contact with the base 2 under atmospheric pressure. Consequently, the surface shape of the base 2 is transferred to the surface of the reflector 1 and a reflective plane having desired shape 15 obtained. When an incident X-rays 4 impinge on the concave mirror 1, sufficient quantity of X-rays 5 reflected on the mirror surface having high smoothness can be condensed. Contrary to dynamic resilient deformation, surface shape of the base 2 is transferred, as it is, to the mirror by this method and thereby a reflective plane having highly accurate surface shape can be obtained by machining the base 2 accurately.

Title: Clock signal generating circuit for semiconductor integrated circuit
Inventor: TAKESHIMA TOSHIO
IPC: H03K17/00
Filed: 1986-10-03
Abstract: PURPOSE:To increase the operation speed by not raising the level of an output signal with one buffer circuit but raising the level of the output signal stepwise with plural buffer circuits to shorten the rise time of the level of the output signal even in case of the use of a voltage source, whose output resistance is relatively high, in the last output stage. CONSTITUTION:When a set signal S0 goes to a high level at a time t1, a buffer circuit B1 is operated to quickly raise an output voltage OT1 up to an about potential V1 of a voltage source 2 at a time t2 after a rise time T1. If a following set signal S1 is set to the high level at a time t3 when the output signal OT1 sufficiently approaches the level V1, the operation of the buffer circuit B1 is stopped and an output terminal (d) of the buffer circuit B1 is brought to the floating state. Meanwhile, the operation of a buffer circuit B2 is started simultaneously to raise the output signal OT1 from the level V1 to a voltage V0 of a voltage source 1 at a time t4. Since the output resistance of the voltage source 1 which gives the output level of the buffer circuit B2 is high, a rise time T2 is longer than the rise time T1. Thus, a time t01 is shortened to be equal to the time T1.

Title: Holding circuit of busy line
Inventor: KAWANISHI KUNIHIKO
IPC: H04M7/00
Filed: 1983-12-15
Abstract: PURPOSE:To prevent the disconnection of a busy line by using a signaling bit latched simultaneously with the generation of alarm to continue the connection of the busy line. CONSTITUTION:A changeover device 20 supplies the output of a 3-bit processing circuit 18 to a terminal CH1 when the output of a slow releasing circuit 25 is at OFF-state, and blocks it when the output is in ON-state. Moreover, a changeover device 21 transmits an output of a latch circuit 19 to the terminal CH1 when the output of the circuit 25 is in ON-state, and blocks it when the output is in OFF- state. Thus, the signaling bit of a channel 1 latched by the circuit 19 is fed to the terminal CH1 in place of the signaling bit transmitted so far by the circuit 18. The transmission of the said signaling bit is continued until a prescribed time when the alarm is restored and the output of the circuit 18 is restored normally is elapsed. When the channel 1 is busy, the line is not disconnected but held. The line is not disconnected but maintained similarly when a channel (n) is busy.
